Hi ,
I have bulk loading job.
My job is for User data aggregation.
Before I run Bulk Loading aggregation I want to create regions
UserID looks like this :

I have ~ 50.000.000 users. I run aggregation on daily basis and per day I
have ~ 30 regions.
So The objective is to create 30 regions with more or less equal
distributions.
The question is : What is the best practice to verify start / end key for
regions in my use case?
Thanks in advance
Oleg.
